Hi @Mznina,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand the error code "UA_400_EB000U0422" you're encountering during the setup of your HP DeskJet 4100e All-in-One Printer series on WiFi could be related to network connectivity or configuration issues. 

Here are some steps to troubleshoot and resolve the issue:

1. Restart All Devices

• Turn off your printer, router, and computer.
• Wait for about 30 seconds, then turn on your router first.
• Once your router is fully operational, turn on your printer and computer.

2. Check WiFi Connection

• Make sure your WiFi network is working properly and that you are using a 2.4 GHz network, as some HP printers may not connect to 5 GHz networks.
• Ensure your printer and computer are connected to the same network.

3. Update HP Smart App HP printer setup (HP Smart app)

• Ensure you are using the latest version of the HP Smart app for the setup.
• If you're using an older version, update it from the Microsoft Store (Windows) or App Store (iOS).

4. Printer Reset

• Restore the printer to default network settings:
  1. Turn on the printer.
  2. Press and hold the Wireless button and the Cancel button together for 5 seconds. The Wireless light should start blinking, indicating that the network settings have been reset.

5. Manual Wireless Setup via HP Smart HP printer setup (Wi-Fi network)

• Open the HP Smart app and select the Add Printer option.
• Follow the on-screen instructions to manually connect the printer to your WiFi network.

6. Temporary Disable Security Software

• If you are using any firewall or antivirus software, temporarily disable it during the setup process, as it may interfere with the connection.

7. Reinstall the HP Smart App

• If the error persists, try uninstalling and reinstalling the HP Smart app to ensure a clean installation.

8. Try WPS Setup (If Supported) 

• If your router supports WPS (WiFi Protected Setup), you can try connecting the printer using this method:
  1. Press and hold the Wireless button on the printer for 3 seconds (until the wireless light starts blinking).
  2. Press the WPS button on your router within 2 minutes.
  3. The printer should connect to the network automatically.
